BIL Bank

Founded in 1856, Banque Internationale à Luxembourg (BIL) is one of the oldest banks in Luxembourg and operates a dedicated Wealth Management division serving individuals, families, and entrepreneurs with complex international patrimonial situations. The division positions itself as a full-service private bank with a dedicated private banker model, meaning clients deal with a named relationship manager who coordinates access to internal specialists rather than routing through generalist teams. This structure suits families managing multi-jurisdictional assets who need coordinated advice across tax, succession, and investment in a single relationship.

BIL Wealth Management covers a broad range of services under one roof:

• Discretionary portfolio management and investment advisory (BIL Advisio and BIL Serenio mandates)
• Wealth planning including life insurance, tax services, and succession structuring
• Financing including international mortgage credit and yacht financing
• Corporate finance advisory for entrepreneur clients
• Access to private markets

The bank operates across Luxembourg, Switzerland, France, and China, with a contact intake process that explicitly accommodates residents across Western Europe and beyond. ESG integration is presented as a standing component of the investment approach, not an optional overlay. For family offices or wealthy families anchored in Luxembourg or seeking a Luxembourg-domiciled banking relationship, BIL offers depth in cross-border structuring that a generic European retail bank cannot match. That said, the site discloses no fee structures, minimum asset thresholds, or performance data, so prospective clients must engage directly to understand commercial terms. Families seeking a technology-forward reporting portal or open-architecture custodian may find BIL’s model more relationship-centric than operationally flexible.
